Specification of Letters Patent.

Patented April 8, 1906.

Application filed September 12, 1905. Serial No. 278,194.

Be it known that I, RICHARD M. BEDELL, of the borough of Brooklyn, city of New York, county of Kings, and State of New York, have invented a new and useful Improvement in Linotype-Machines, of which the following is a specification.

This invention rel-ates to machines of the effected by advancing the long wedges of the spacers througl'i the line until it is expanded tightly between j the jaws. The, matrices while in casting position must be alincd facewise by the pressure of the mold and vertically by the rise of the elevator in which the line is carried. These actions demand that the line shall be relieved from end pressure in order to reduce the friction between the matrices and permit them to move in relation to one another and the line finally confined again to the predetermined length. Heretofore this has been secured by means of a jawa-ctuating screw-receiving motion from a pin ion and a rack-bar actuated by one of the levers which moves the justifying wedges or spacers. In practice the wear of the screw and the other parts, the excessive strain to which they are subjected, and other causes result in the failure of the jaws to assume the precise position required and as a consequence the slugs are of improper length.

The present invention relates to a wedge mechanism for controlling the movable jaw to be incorporated in linotype-machines of the present commercial form without change in the cams or actuating-levers.

I have limited the drawings to those parts of the machine with which the invention is immediately associated. As to all other parts they may beof ordinary or any suitable construction.

Referring to the drawings, Figure l is an inside face view of the line-clamping jaws and attendant parts, commonly known as the vise, in the position which they occupy when the composed line is presented between the jaws. Fig. 2 is a similar view with the parts at a later stage of theopcmtion. Fig. 3 is a similar view with the parts in the position which they occupy when the line has been justified. Fig. 4 is a cross-section in the line 4 4 of Figs. 1, 2, 3, 5, and 7. Fig. is a horizontal section in the line 55, Figs. 1, 6, and 7. Fig. 6 is an end elevation of the vise looking from the left side. F ig. 7 is a front elevation of the same. Fig. 5 is a vertical section in the line 8 8, Fig. 6. Fig. 9 is a section on line 9 9, Figs. 1 and b.

Referring to the drawings, A. represents the upper part of the stationary vise-frame forming a part of the main frame of the machine.

B and (l are the two jaws for confining the matrix-line endwise. The jaw B is fixed nor mally in position; but the jaw (I is sustained.

by the tongue on its side seated in the hori* zontal groove (1. in the frame, so that the jaw maybe moved forward and backward.

The composed line consists of matrices l) and intermediate spacers or justifiers E, each consisting, as usual, of two oppositely-ta pered wedges connected by a sliding joint, so that by moving the longer wedge past the shorter one held fast in the line the spacers may be increased in thickness at the operative point and the matrix-line thus elongated or justified tightly between the jaws to the predetermined length, as usual.

The matrix-line, sustained, as usual, on that part of the machine known as the first elevator, is lowered to its position between the confining-jaws, as shown in Figs. 2 and 3, and while it is thus located the justifying, alining, and casting operations occur.

The present improvement has reference to means for supporting and adjusting the j awseat. The supporting means consist of a horizontal rod G, circumferentially toothed, seated at one end directly against the jaw O and extending thence outward through the block H, which is in turn connected rigidly, but adjustably, to the rod by a verticallytoothed pin l, which is extended downward through the block H inv engagement with the teeth of the rod.

The block H, which serves as a rigid supthe same endwise, is in its turn supported by a vertical wedge J, slotted vertically to straddle the rod and seated at its outer side against a rigid support. This su port may be a bearing-surface on the main ame; but in order to compensate for the wear of parts and to permit very accurate adjustment of the jaw it 'is preferred to seat the outer side of the wedge a ainst a bearingpiece K, seated against the end of a heavy tubular screw L, threaded into the main frame and loosely surrounding the rod G.

The wedge J is constructed, as shown, with two inclined or wedge surfaces la and 7c, the former at the upper end being short and abrupt, while the other is long and of gradual inclination or ta er. The wedge is extended dovmward and s otted at its lower end k, as

shown in Fi 6, for connection with the lever ordinari y employed for operating the jaw closing screw and the justifying bar, this lever being designated p in Patent N 0. 436,532.

A spring k is extended from the arm on the I wedge to the main frame, as shown in-Fig. 6, so that it serves to drive the wedge upward whenever it is relieved from the downward action of the controlling-lever, being constantly urged upward by a spring and depressed at suitable intervals by a cam, as usual.

It will be observed that the iece K gives solid support to the blockH an that the latter in turn supports the rod G, which gives direct supglqrt to the jaw 0, these several parts sta g directly behind the jaw and in the line in which pressure is applied thereto. When normal, the wedge stands in its lowermost position, as shown in Fig.- 1, with its upper surface 7c seated a ainst the correspondm surface on block In this osition', of the parts, the wedge being in its owermost position, the distance between the jaw C and its companion B is exactly equal to the length of the line re' uired. While the jaws are in this position, t e unjustified ma trix-line of less than the final length is lowered between the jaws to the position as shown in Fig. 1. The wedge J then rises to the position shown in Fig. 2, slightly releasing the jaw C, but continues its upward movement until it arrives at'the position shown in Fig. 3, in which position it again supports the jaw C in the same osition as in Fig. 1. j

Whenthe e has been lowered between the jaws and the wedge is in the osition shown in-Fig. 1, the bar M .rises'in itsmclined position; the spacing -wedgeslupward and efiecting approximate justification of the line. The we g'e J next r1ses sufficiently to relieve the jaw O and the matrix-line from pressure, as shown in Fig.1 2, and the mold is "at this time moved forward against the faces or edges of the matrices, thus effecting the alinement of the matrices facewise, while they are free, or substantially so, from frictionon their side faces, and at the same time, or practically so, the usual elevator sustaining the matrix-line rises, so that the lower ears of the matrices are pressed a ainst the edge of the mold, and this brings t e characters into alinement horizontally. The wedge next rises still farther, bringing into action the lower surface It, so that the line is again confined to the exact len th required. While the line is thus confined, the bar M rises in a horizontal 1position, as shown in Fig. 3, again acting on t e spacer-wedges and effecting the final justification of the line. The casting operation then takes place. The wedge descends momentarily to the osition shown in Fig. 2, relieving the ,line om pressure, so that it maybe lifted out from between the jaws for transferrence to the distributing mechanism. The wedges then descend to the first position, as shown in Fi l, reparatory to the entrance of the next line?) the jaws.

- It is to be particularly noted that during each ,of the justifying actions sustained by the line at the first and second level of the space-bands, which action oeears'as in'Patent No. 436,532, the jaws are firmly supported at a distance apart exactly equal to the length of the line required.

etween.

In order to change the measure or length of line, it is only necessary to lift the pin I until its teeth disengage from the rod G, which may then be moved forward or backward in relation to block H and again secured to the latterv by pin 1. This adjustment of the pin in relation ,to the supporting-block is the same as in United States patent to Rogers, No. 619,441.

I commonl construct'the rod G with its teeth one-hal em in len th; but they may be varied in len th at will. By turning the screw L, there y changingthe position of the support K, I am enabled :tocompensate for wear on parts and also to adjust the jaw for measures involving fractions of less thanonehalf an em. The wedge is provided in the present instance with two. inclined surfaces simply in order that it may be used in connection with the operatingileams and levers as now employed in the specially-designed cams the upper surface otypemachine. In constructing new machlnes contamm may beomitted and the necessary movements of bloc-ll; H efiected by giving the proper upward or downward movement to the wedge and only the surface 7c.

order to permit the operator to effect speedy adjustment of the jaw C for different measures without leaving-his seat at the keyboard, I pivot to the jaw C a. hand-lever 0, such as shownfin Figs. 4 and 5, curved downward and forward, so that it can be laterally grasped by the operator. I provide this lever w th a pointer 0, adapted to travel over a scale 0 graduated to one-fourth ems and one-halt ems and attached to the stationary frame, as shown in Figs. 4, 5, and 7 The inner end of this lever is notched, so that when its forward end is lifted it will enter the groove 9 in rod G. The pin I being first withdrawn to release the rod G, the adjustment of the jaw C and the rod may be instantly e'fiected for any required measure by moving the lever laterally until the pointer arrives at the proper graduation on the scale, after which it is only necessary to lower the pin I into engagement with the rod.

Having described my invention, what I claim is 1. In a linotype-machine the combination of the line-confining jaw, a rigid bearing and an intermediate sliding wedge acting to sustain the jaw in definite position and to release the same. i1

2. In a linotype-machine,the combination of the movable jaw to confine the matrixline, a 'fixed bearing, and an intermediate mechanically-actuated Wed e.

3. The combination of t e line-confining jaw a mechanically-actuated. wedge and an adjustable bearing for the wedge.

4. In a linotype-machine a movable lineconiining jaw in combination witha mechanically-actuated wedge and an intermediate adjustable connection.

5. In a linotype machine the cornbmation of the movable jaw, the wedge, a rigid support therefor, a block bearing on the wedge and an adjustable rod connecting the block' and the jaw.

6. In combination the jaw, the rod, the block secured to therod and the wedge-bearing surfaces 71: and k. j

7. In a lin'otype-machine and in combination, the jaw, the toothed rod, the block, means adjustably connecting the rod and block, the wedge and the tubular screw sustaining the wedge.

8. In a linotype-machine matrices, expang 1 sible wedge-spacers, and jaws to confine'the line in combination with means for adjusting the jaws to the length of the final line bef ore 5-0 and during a first expansion of the spacers, then. releasing the jaw to permit alinement of the matrices, tlien restoring the originalrela- .tion of the jaws prior to a second and final adjustment of the spacers.

testimony whereof Ihereunto set my hand, this 5th day of September, 1905', in the presence of two attestin witnesses.
